25 × x = 45
or 25÷100 × x= 45
multiplying both sides by 100 and dividing both sides by 25, we have x = 45×100÷25
therefore, x = 180
( if you use a calculator simply enter 45×100÷ 25)
1.) v=(l)(w)(h)
V=(9)(9)(9)
V=(81)(9)
V=729in^3
2.) (I forget if this is the real equation to this but this would give you the same answer)
